Frequently Asked QuestionsWireless Analog Video Systems
1. What makes up a Trango wireless video system? An analog point-to-point system includes a transmitter, a receiver, two antennas, and AC adapters. A basic Ethernet system includes a subscriber unit, an access point, and external antennas, if necessary. Systems can be more complex depending on number of cameras, range, PTZ control requirements, etc. See our selection guide for more information. 2. How does an analog wireless video system work? In a basic wireless video system, standard video and audio signals are input to the transmitter. The transmitter transmits these signals wirelessly via a microwave carrier to the receiver. The receiver outputs a standard video and audio signal. 3. Does the user require an FCC license to operate Trango Systems wireless video equipment? No. Trango Systems' wireless video transmission equipment has been certified by the FCC under Part 15 regulations and require no User License. Our equipment is also certified for license free use in Canada. 4. Do installations require line-of-sight between transmitters and receivers? All point-to-point high frequency wireless solutions, with the exception of the M900S, clear line of sight between antennas enables optimal performance. It is sometimes possible to transmit short distances through loose vegetation, but ideally, antennas should be mounted above all obstructions. For very short distances (500 feet or less), it is possible to transmit through several walls as long as they are not constructed of concrete or metal materials. Use of repeaters helps mitigate line-of-sight problems. Instead of requiring clear line of sight to the ultimate destination, a receiver/transmitter combo can be placed at the point of obstruction between the camera and the ultimate receiver location. 5. Do Trango wireless products interfere with other wireless devices and vice-versa? Our products are governed by FCC Part 15 regulations. All wireless equipment operating in the 900 MHz and the 2.4, 5 GHz unlicensed bands must adhere to Part 15 regulations. Part 15 regulations are designed to ensure that no one device can dominate the spectrum. However, to ensure that interference will not be an issue, a thorough site survey should be conducted prior to installation of equipment. 6. Is Trango equipment compatible with other CCTV, video, and sound equipment? Trango equipment utilizes standard industry formats such as NTSC and PAL for video (color or black-and-white) and RS232, RS422, and RS485 for data to ensure compatibility with all major brands of CCTV equipment. 7. Is it possible to control PTZ cameras wirelessly? Yes. Either the SDR900H, Falcon PLUS, or Eagle PLUS can be installed for the purpose of controlling PTZ cameras. 8. What type of antennas are required? The type of antenna will depend on the RF frequency being used and the distance needed to transmit. Therefore the further the distance needed to transmit, the stronger the gain of the antenna will be needed for the application. See our Antennas guide for more information. 9. What is an "omni-directional antenna"? A directional antenna transmits like a beam of light from a flashlight towards the receiver. An omni-directional antenna radiates the radio frequency in all directions off the antenna, like ripples caused by a rock thrown in a pond. 10. Can I extend the length of the cable from the radio to the antenna? Generally it is not recommended, though it depends on the cable and the frequency you are using. In general the longer the cable between the antenna and receiver the greater the loss of signal strength. 11. How far can the transmitter be from the camera? As far as the cable type will allow you before losing one volt, peak to peak. Generally RG-59 cable will allow you 750ft before the video quality decreases. 12. What types of devices will interfere with a wireless video system? Some digital cellular phones, fluorescent lighting, and cordless phones may or may not have an effect on any 900MHz transmitters. Microwave ovens in close proximity to 2.4GHz transmitters can cause interference, as can other wireless products in the same ISM band (such as cordless phones or WLANs) if they are using the same channel as our transmitter. 13. Do specified ranges account for rain and snow which may degrade the transmit signal? Yes, ranges specified for each product include a fade margin to account for rain and snow. |
